Figure 10 is the overall perspective view of the another one embodiment of groove type solar Accumulated Heat Units of the present invention.In Figure 10,48 represent that eddy current control module, 49 represents cloth shape member.In addition, in the illustrated structural member of Figure 10, for the structural member mark identical with the illustrated structure of Fig. 1 to Fig. 3 identical with reference to numbering.
In the groove type solar Accumulated Heat Units of the another one embodiment of the present invention shown in Figure 10, the mobile eddy current control module 48 of controlling of the eddy current that the peripheral portion place of this curved mirror 1 in the direction that the curvature of the curve form to curved mirror 1 changes produces, is configured to have the mode of the cloth shape member 49 on the peripheral portion that is arranged on curved mirror 1.This cloth shape member 49 is configured to be configured to, the in the situation that of in curved mirror 1 is arranged at air-flow, on the peripheral portion of curved mirror 1, spin out along flowing of air-flow, thereby realize the rectification of the eddy current that the peripheral portion place of curved mirror 1 is produced, suppress to result from the generation of the eddy current on this peripheral portion, and then can avoid the damaged situation of the curved mirror 1 causing because of vortex-induced vibration.
Above, according to the present invention, by being configured on the heat accumulating pipe in front of this curved mirror sunshine being concentrated on curved mirror, and in the groove type solar Accumulated Heat Units that flowing liquid among this heat accumulating pipe is heated, on the peripheral portion of this curved mirror in the direction changing in the curvature of the curve form of curved mirror, the mobile eddy current control module of controlling of the eddy current to producing in this peripheral portion place is set, even if thereby also can avoid the damaged situation of the curved mirror causing because of vortex-induced vibration when to the higher resistance to wind speed specification of this matching requirements.
